Classification: 27030000 [AAB609009]

Preferred name 27-03 Transformer, converter, coil
Definition transformer is a structural component (mains transformer) or a facility (transformer station) which is used for the increase or the reduction of alternating currents. Converters pertain to the technical appliances for converting physical quantities, i.e. assembly groups which change electric potentials or circuits which convert between different electrical quantities. A coil is part of a technical inductance, i.e. an inductive passive structural component, e.g. a transformer. Main group 27030000 is structured by the fields of application and measurements of different transformers as well as method and capacity of their electrical transmission. Another section is reserved for the Petersen coils. Furthermore there is a differentiation between components and accessories of the transformers, their assembly, service, inspection and maintenance
